He completed a Ph.D. at Lin- coln University on the taxonomy and systematics of New Zealand Lycosidae, a major part of which was published as a revision as Fauna of New Zealand 44. After completing his thesis he spent nine months at AgResearch as a postdoctoral research fellow investigating the genetics of hymenopteran parasitoids of weevil pests. From 2003 to 2005, Cor was a postdoctoral associate at San Diego State University, U.S.A., where he worked on developing new molecular markers for inferring deep phylogenetic rela- tionships in spiders. At the end of 2005 he returned to New Zealand and joined the Biosecurity Group at AgResearch, Lincoln where he is currently employed as a scientist. Cor is especially interested in the systematics of New Zealand spiders and he is the adjunct curator of spi- ders at the Entomology Research Museum at Lincoln Uni- versity. He has recently published an annotated key to the spider families of New Zealand with Pierre Paquin and Nadine Dupérré. Contributor Nadine Dupérré is from Québec, Canada. She completed a Bachelor of Science at Université de Montréal in 1997. She began illustrating spiders in 1998 and to date has produced over 5000 illustrations. Nadine is probably best known amongst arachnologists for her illus- trations in the book “Spiders of North America: an Identi- fication Manual”.

Jacob Ætaki Fauna of New Zealand 64 7 ABSTRACT Four species of Pisauridae, all in the genus Dolomedes Latreille, 1804, are found in New Zealand; D. minor L. Koch, 1876 nomen protectum (=D. lateralis White, 1849, new synonymy, nomen oblitum, D. sagittiger White, 1849, new synonymy, D. imperiosus L. Koch, 1876, and D. tridentatus Hogg, 1911, new synonymy), D. aquaticus Goyen, 1888, D. schauinslandi Simon, 1899 (=D. huttoni Hogg, 1908, D. trippi Hogg, 1908, new synonymies) and D. dondalei sp. nov. The genus and all species are described, with information on synonymy, type data, material examined, and geographical distribution. Habitus images of adults, illustrations of important structural features, and distribution maps are provided. A key to adults is given. A molecular phylogenetic analysis examining the relationships of New Zealand species in the genus Dolomedes is presented. Mitochondrial DNA (cytochrome c oxidase subunit 1 – COI) and nuclear DNA (actin 5C) was sequenced from all four New Zealand Dolomedes species. COI divergence between species was low and introgression appears to have occurred between D. minor and D. aquaticus. Keywords.
